Hi Marc,

   Thanks for your kindly reminder:-), I understood a little more. After
adding the .select callback, we can assign an interrupt to one of irq
domains from interrupt specifier. Thanks a lot.

ChangeLogs:
V2->V3:
	*impletement .xlate and .select callback.

V1->V2:
	*squash patches:
		drivers/irqchip: enable INTMUX interrupt controller driver
 		drivers/irqchip: add NXP INTMUX interrupt multiplexer support
	*remove properity "fsl,intmux_chans", only support channel 0 by
	default.
	*delete two unused macros.
	*align the various field in struct intmux_data.
	*turn to spin lock _irqsave version.
	*delete struct intmux_irqchip_data.
	*disable interrupt in probe stage and clear pending status in remove
	stage.
